i really like this skin very much, great work!
I have noticed the following in the release notes of ButtonFacade (r344):

For skins to use the new attributes, a new skin data table key is required. This new key is called LBF_Version. The value of this key MUST be set to 40000 (number) in order to use the new attributes. Older skins need no modifications and will function as they have until after Cataclysm is released, at which point they will *have* to be updated.

I really hope that your excellent skin will continue working when Cataclysm goes live
